laravel phpUnit phpStorm docker connection

i have set up of php/mysql/apache/laravel stack through the docker without problems, everything up and running. i have set up docker in phpStorm as well- everything works good.

now im trying to set up phpUnit in phpStorm, which i never set up before especially with the docker container so error could be very simple i just cant understand what is wrong and where :(

when i run any test (which is working well for sure) i'm receiving this kind of errors:

it looks like smth is wrong with the DB connection settings but i cant understand what is wrong because the only change from what main application uses is database name and database with this name exists

here is how i set up phpUnit in phpStorm, as you can see the path to the phpunit.xml is set up and everything look good

here is .env

DB_CONNECTION=mysql
DB_HOST=xcard_db
DB_PORT=3306
DB_DATABASE=xcard
DB_TEST_DATABASE=xcard_test
DB_USERNAME=root
DB_PASSWORD=jackjack

this is laravel config/database.php, as you can see i use DB_TEST_DATABASE and this is the only difference (i have cleaned some unnecessary settings, errors are the same with or without them)

        'xcard_test' => [
            'driver' => 'mysql',
            'host' => env('DB_HOST', '127.0.0.1'),
            'port' => env('DB_PORT', '3306'),
            'database' => env('DB_TEST_DATABASE', 'forge'),
            'username' => env('DB_USERNAME', 'forge'),
            'password' => env('DB_PASSWORD', ''),
            'charset' => 'utf8mb4',
            'collation' => 'utf8mb4_unicode_ci',
            'prefix' => '',
            'prefix_indexes' => true,
            'strict' => true,
        ],

        'mysql' => [
            'driver' => 'mysql',
            'url' => env('DATABASE_URL'),
            'host' => env('DB_HOST', '127.0.0.1'),
            'port' => env('DB_PORT', '3306'),
            'database' => env('DB_DATABASE', 'forge'),
            'username' => env('DB_USERNAME', 'forge'),
            'password' => env('DB_PASSWORD', ''),
            'unix_socket' => env('DB_SOCKET', ''),
            'charset' => 'utf8mb4',
            'collation' => 'utf8mb4_unicode_ci',
            'prefix' => '',
            'prefix_indexes' => true,
            'strict' => true,
            'engine' => null,
            'options' => extension_loaded('pdo_mysql') ? array_filter([
                PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
            ]) : [],
        ],

and here is my phpunit.xml

<?xml version="1.0" encoding="UTF-8"?>
